Eco Start/Stop might have an actual useful purpose
I probably dislike Eco Start/Stop about as much as anyone, but it may actually serve a useful purpose - early warning of pending system failures.
Eco Start/Stop stopped working three in the 6 years I’ve owned the car, and all three times, a couple of months later I had 1) Auxiliary Battery failure, 2) Main Battery failure, and 3) front SAM failure. I guess it has its sensors poking into most of the car’s systems, and any problems anywhere are enough to prevent Eco Start/Stop from shutting down the engine at stops, even if there are no other indications of upcoming problems.
It might be a good idea to occasionally let it do its thing, just to confirm it is working and there aren’t (hopefully) any other problems that may be appearing soon.

I don't know what to do.
